Are you sure current driver works now? I am absolutely sure that the driver works on a 2GB ROCK3A board. Unfortunately, I don't have a device with 4GB or more memory and I cannot test the driver with such a device. As the documentation for the RGA2 is the same in the TRM of the rk3288 and rk3568, I would guess that the driver doesn't work on a rk3288 with more than 4GB (if there is such a thing) either and the driver needs to be fixed for both SoCs.
